Quantum lattice gates could replace thousands of control cycles with one, reducing the time fragile quantum information stays ...

Quantum error correction must detect and correct errors without directly reading the quantum information. Classical ...

Associate Professor Kenta Kasai of Science Tokyo has developed a high-rate quantum low-density parity-check (LDPC) code by ...

Scientists at the Institute of Science Tokyo have announced a breakthrough in quantum error correction that could bring a large-scale quantum computer closer to ...

A single-period Floquet control method using "quantum lattice gates" to execute operations on bosonic quantum codes over a ...

In mathematics and getting dressed, some processes are commutative, while others are noncommutative. Commutative means the order doesn't matter (3 + 2 is the same as 2 + 3, and it doesn't matter which ...

A research team has created a quantum logic gate that uses fewer qubits by encoding them with the powerful GKP error-correction code. By entangling quantum vibrations inside a single atom, they ...

Researchers have found a way to perform certain quantum operations more than 1,000 times faster, cutting thousands of ...

"Our quantum error-correcting code has a greater than 1/2 code rate, targeting hundreds of thousands of logical qubits," explains Kasai. "Moreover, its decoding complexity is proportional to the ...

Classical computing has operated as the fundamental power behind our digital world for many decades. Modern civilization relies on classical systems to operate smartphones and global financial ...
